Eleanor was curious if triangles DEF and GHI were similar, so he tried to map one figure onto the other using rigid transformations Eleanor concluded "It's not possible to map triangle DEF on GHI using a sequence of rigid transformations, so the triangles are not similar. ... So the triangles are similar.
It is B. One more transformation — a dilation — would map \triangle DEF△DEFtriangle, D, E, F onto \triangle GHI△GHItriangle, G, H, I. So the triangles are similar.
